Abstract

The invention relates to the gearing of a gearwheel having a plurality of teeth. The gearwheel has a useful area and a base area of the particular tooth flank form. Viewed in normal section, the tooth base area extends from a base circle up to a useful circle. The tooth flanks of adjacent teeth in normal section are each implemented as symmetrical to one another, the axis of symmetry intersecting the base circle in the base point. According to the invention, the tooth flanks are implemented in the tooth base area as a tangent function from a relevant diameter. The tangent function merges at the relevant diameter in a constant tangent into the tooth flank form of the useful area. The tangent function merges in the tooth base area in a constant tangent into an orbit, which is tangentially applied in the base point to the base circle. Significant increases of the tooth base strength may thus be achieved.
